Subject: [PATCH] libsepol/cil: Destroy classperm list when resetting map perms
|
|
|
1ae9de |
|
|
|
1ae9de |
Map perms share the same struct as regular perms, but only the
|
|
|
1ae9de |
map perms use the classperms field. This field is a pointer to a
|
|
|
1ae9de |
list of classperms that is created and added to when resolving
|
|
|
1ae9de |
classmapping rules, so the map permission doesn't own any of the
|
|
|
1ae9de |
data in the list and this list should be destroyed when the AST is
|
|
|
1ae9de |
reset.
|
|
|
1ae9de |
|
|
|
1ae9de |
When resetting a perm, destroy the classperms list without destroying
|
|
|
1ae9de |
the data in the list.
